Description of a prototype closed-circuit television system (CCTV), developed at RAND, for helping the visually handicapped to read and write. The CCTV system, which consists of a TV monitor and camera, camera-positioning equipment, and a working surface, increases image magnification (from 1.4x to 31.7x), amplifies light, and heightens contrasts. It permits the user to track printed or handwritten material across a line, to adjust the position of the monitor, and to change the vertical plane of the camera to accommodate his individual writing habits. Among the major benefits provided by CCTV would be those of restoring privacy and independence, as well as the ability to compete for jobs. Modifications are planned to improve the usefulness of the device, such as more compact construction. 20 pp.
